England's unbroken half-century opening stand more than doubled their lead on the third morning of the fourth Ashes Test at the MCG.
Alastair Cook dominated the scoring, in company with Michael Carberry, bagging 40 of their first 50 runs together after Brad Haddin (65) first inflicted a little more frustration on the tourists in a last-wicket stand of 40 with Nathan Lyon in Australia's 204 all out.
Cook was immediately fluent in England's second innings as he helped his team move to 54 without loss - 105 runs in front - and, in doing so, became the sixth Englishman to pass 8,000 Test runs.
But for Carberry, after an involuntary single from the first ball he faced via a leading edge into the off side off Ryan Harris, there were 36 dots before a memorable back-foot boundary past cover off Shane Watson.
Wicketkeeper-batsman Haddin had earlier passed 50 for the fifth time in a series the hosts lead 3-0, with the Ashes urn in the bag already.
Haddin and Lyon punctured some of England's mid-match momentum, keeping them out in the field for almost three quarters of an hour of a glorious morning.
There were six fours and a six in Haddin's two-hour half-century, from 59 balls - and Lyon was no silent partner either, mixing in some useful shots and assured defence between the inevitable plays and misses from a number 11.
Finally, though, the short ball worked for James Anderson (four for 67) when he had top-scorer Haddin pulling out of a hook and looping a simple catch to his opposite number Jonny Bairstow.
